Nowadays, with the rapid development of IT and information industry, cell phones play a dominant role in people’s life.On the one hand, the mobile phone is portable and convenient. Being wireless, you can carry them everywhere with great ease. You can reach a person wherever and however far away he is. On the other hand, it is a friend indeed. Whenever you come across trouble, you can call for help immediately.
However, just as every coin has two sides, the cell phone also has its many disadvantages. Some people complain that mobile phones give unpleasant noise on some important occasions when the owner forgets to turn them off. And it also cuts into people’s spare time, because with the mobile phone the boss can easily reach them and call them to duty during their spare time. Worst of all, the electromagnetic wave emitted from the phone is said to be harmful to people’s health and does often cause headaches to the owner.
